A man travels through time to become the three-hundred-jin Crown Prince of Great Ming, Zhu Gaochi. Starting out facing a hot-tempered Zhu Di, he relies on modern thinking for hard-core survival. On the surface, he plays dumb and slacks off, but turns around to dump government affairs onto Prince Han and fiercely controls the Jinyiwei commander Ji Gang. He also opens shops to engage in hunger marketing to get rich, cleverly resolves the emotional knot of Emperor Jianwen, and strongly promotes the Great Voyage to monopolize maritime trade, achieving dimensional dominance over Great Ming amidst the chaotic daily life of the Zhu family!
